Radeon RX 540 vs Quadro K620 specs and performance

For gaming, the Quadro K620 graphics card is better than the Radeon RX 540 in our tests.

In our comparison, the Radeon RX 540 has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the Radeon RX 540 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, the Radeon RX 540 has significantly more memory with 4 GiB of memory compared to 2 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In conclusion, all specs and GPU benchmarks considered, will recommend the Quadro K620 over the Radeon RX 540.
